Whenever working near the logic board, it is always wise to first disconnect the battery to avoid short circuits.

If present, grab the plastic tab attached to the battery connector and pull it toward the front edge of the device. For Late-2011 models the battery connector will not have a tab and is simply a plug that inserts straight down into the motherboard--to remove pry the plug straight up.

If the plastic tab is missing, use a spudger to pry the connector up from its socket.

Before disconnecting the camera cable, a small plastic retainer stuck to the logic board must first be moved out of the way. In late-2011 models you can skip this step because there is not a plastic retainer on the camera cable connector.

Use the tip of a spudger to push the small plastic cable retainer away from the camera cable socket for enough clearance to remove the camera cable.

Use the flat end of a spudger to peel the thin plastic cover off the top and sides of the Bluetooth board housing. For late-2011 models check out the other picture because the connector location is in a totally different location.

Lift the black plastic flap attached to the display data cable retainer and rotate it toward the DC-In side of the MacBook.

Pull the display data cable out of its socket.

The display data cable socket is very fragile. Do not lift the connector upward as you disconnect it, as the socket may break off the logic board. Pull the cable parallel to the face of the logic board.

Grab the upper case with your right hand and rotate it slightly toward the top of the display so the upper display bracket clears the edge of the upper case.

Rotate the display slightly away from the upper case.

Lift the display up and away from the upper case, minding any brackets or cables that may get caught.

During reassembly, fit the display into place and install the display bracket Torx screws, then close the lid and lay the laptop upside-down to check the alignment of the screen to the body. If necessary, loosen the screws and realign the display before tightening.
